SPECIFICATION formingpart of Letters Patent No. 293,365, dated February 12, 1884.

Application filed May 29, 1883. (No model.)

To @ZZ whom it may concern.-

Be it known that I, BENJAMIN SCOTT, of Bloomington, in the county of McLean, and in the State of Illinois, have invented certain new and useful Improvements in Corn-Planters; and I do hereby declare that the following is a full, clear, andeXaC- t description thereof, referenee being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification, and in which- I Figure l represents. a top view or plan of my improved machine; Fig. 2, a rear elevation of the same; Fig. 3, a side elevation of the left side of the machine, or sectional view through the line .r :o of Fig. 1; Fig. 4, a longitudinahvertical central section; Figs. 5, 6, 7, S, 9, 10, 11, 12, 13, and 14, sectional and detail views to be hereinafter .referred to.

This invention relates to certain new and useful improvements in machines for planting corn at any desired width between the rows, so that the corn can beplanted both ways without the aid of ropes, wires, check-lines, or hand-levers; and the four important features of the invention are, rst, in an auto- Amatic sulky corn-planter adapted to work on uneven surfaces; secondly, in an automatic revolving drop; thirdly, in a mathematical indicator that will at all times denote the starting-point of the machine; and, fourthly, in the mechanism for raising the operating parts of the machine; and to this end the invention consists in novel features of construction and combination and arrangement of parts, all as will be' hereinafter fully described, and set forth in the claims hereto annexed.

InV the drawings, A represents theV main frame of the machine, composed of the longitudinal beams a a a and transverse beams a a. Upon the rear end of the central beam a is mounted the drivers or operators seat c2, andto the front end of said beam andtransverse beam a is secured the draft pole or tongue ai by a fastening-bolt and braces, in the usual manner. i

A A represent longitudinal beams, connected to the transverse slotted beams a a by bolts at and castings a5, all as clearly shown in Fig. 1. These beams carry and support the operatin g machinery, and can be adj usted latcured to the outer beams, a a) by means of j screw-bolts ZP, the stems of which extend out-- ward and pass through the spindles and hubs of the supporting-wheels, when screw-,nuts put on the ends of said screw-bolts will press the spindles against said castings, and hold them lfirmly in position while permitting the sup porting-wheels to revolve thereon, as clearly AShown in Figs. 1 and 9. By loosening said nuts the spindles and wheels can be vertically adjusted to raise or lower the frame, forf a purpose to be hereinafter described.

c c represent4 boxes with V-shaped notches on sides and bottom, (see Fig. 5,) and which are adapted to be vertically adjusted in the slots b3 b3 through the upper portions of the castings b b.

C represents the main shaft, journaled in said boxes c' c, and passing through the hubs `of flanged disks C C and hollow tube e', said tube passing through the central castings, 2 2. and secured thereto by set-screws. The disks C C are closedon one side, and adjustably connected to the shaft C' byset-screws, so as to be laterally adjusted thereon, and are provided with a series of radiating adjustable arms or spokes, D, having steel points d, that engage the ground, and form, in connection with the disks C C', the motive power for operating the corn-dropping1 mechanism. The longitudinal adjustment of the spokesI D permits of the corn being dropped at longer or shorter distances apart, and whenever adjusted the supporting-wheels should also be vertically adjusted to correspond with the adjustment of the spokes, so that the latter will have at any adjustment the same uniform bearing or engagement with the ground.

EE represent flanged disks, having one of their sides closed, and arranged inside of and secured to the hubs of the disksC G by setscrews. The disks E E are provided with oblique holes e through them, and arranged in three divisions of four holes each, and at ro:

equal distances apart, the holes inkeach divis-- ion varying in size from one-half to one-sixteenth inch, the smaller holes being arranged uniformly in advance of the larger ones, all as clearly shown in Figs. 10, 1l, and 14. The iianges or rims of the disks E E are provided with circular recesses e (see Fig. 14) on their inner surfaces, into which are sprang bands e2 e2, (see Fig. 12,) corresponding'with the interior circumference of said disks. These bands are provided with three holes, e3, of the same size as the largest holes, e, through disks E, and at equal distances apart, and are adjustably secured in said ldisks ley-threaded bolts e, secured thereto, and working through slots c5 in the flanges of said disks,'and secured' By vmovirigthe bands el around in the'disks'E,l the holes will cover any of the diffei'entlsi'zed" in any desired position by screw-nuts e holes in ,saidl disks, andthereby regulate the number of grains of corn desired to bedr'oppedI to form `a'hill.v

F F represent troughed' or,l seniicircular shaped hoppers, tapering and incliningdown` ward from their inner towar'dtheiroutenor" enlarged ends.' TheseA hoppers areprov'ided with bearings ff, for the reception'of the shaft' C, and the be'aringsf are 'secured fonhubs ofi disks C C and against 'tliehiibs 'bf' disks E'by collars f2 inside ofhubsof disks C", secured'by bearing' against the castings 2, and securedo'n the hollow tubes 'by set-screws, byV which the hoppers areheld in position, while the hubs" of disks E revolve inside of thebearingsf and the hubs of disks'C outside of them. The' inclined and taperingfform of hoppers permits the corn to pass inside of the disksE, which are on the same'level as the hoppers, which'` have rabbets or offsets f2 on their enlarged ends, (see Fig. 7,) which t" outside of and around thelowerhalf ends'of said disks E,

and which-'rabbeis or offsets connect with pipes or conductors f3, (see Figi. 3,) extendingdownr ward inside of the ilangesor rims "of the disks C, so that the corn passing'through' disks'E is discharged inside' of the flanges or rims of the disks C, which have three holes, c2, through them, arranged at equal distancesapart, but alternatingfwith` the-holesthrough disks E, the corn lying in the flanges'of the disks C G until th'ey'v-come around opposite'the'pip'es'or conductors y, (secured to castings 'g,) through` which the corn is discharged, andfalls'down through the heels of the cutters'G into the fur rows formed by said cutters.

I-I represents hammers, (shown in Fig.4 and"v detail'views, Fig'. 13,)wh`ich' are piv'oted at their ends inside of the centers of `thel hoppers F, and theirlarger ends restingin the disks E, and having beveled shoulders 'h onY their nn-v der sides inclinin'g toward th'e'hoppers, so-that as thedisks E fill any one of the three holes'e3 in bands e2 with vcorn in passingunder'the center or bottom of the hoppers 'thebeveled shoulders on hammers will throw any loose corn backtoward the centers or bottms of the hoppers, while the corn in said holes will 'pass downward through the holes in disks E and into and be discharged through pipes or conductors f3 onto the fianges or rims of the disks C. Should any of the holes in bands cl be very full of corn, or the grains stand up on ends, the hammer H will be raised and pass the corn under and immediately fallback into position without cutting the corn, while obviating clogging of the holes in said bands and disks.

The drawings are made to represent the machine adjusted to its narrowest capacity, so that when it is desired to adjust the mechanism 'to plant corn with the rows farther apart the bolts or set-screws on the beams A A/ are loosened, as also the set-screws of hoppers. and disks U', when the beams, hoppers, and disks C can be moved outward on the shaft C, the slnaller'ends of hopper being of sufficient len gth to'move onthe hollow tubes c.

I I represent two halfcircular or bent wroughtiron rods or bows, the lower threadedends of which pass down through holes in the castings 2, and blocks bolted on central beam, a, and secured in position by screwnuts.-

jj 'represent the hubs of a gear-wheel, J, having lhexagonal ends, (see Figs. 1 and 2,) upon which are sprung the forked ends of a lever, 4, having hexagonal openings,through them, and-which forked ends form a connection between said hubs.

Krepresents a vertical toothed bar meshing with gear-wheel J, so that when lever 4 is pulled backward the gear-wheel will be revolved and travel up said toothed bar, thereby raising -tube c and castings 2, having tubes c3, mounted on and slidingnp the guide-rods l, carrying with it the shaft C, thereby raising all that isl connected to it, being the hoppersand disks C and E, while the boXes c travel up the vertical slots b3 in castings b', and the spring-latch 7 on lever'4, engaging any of the notches in curved bar 6', Vwill hold said lever at any desired point, all as clearly shown in dotted lines Fig. 4, andv by means of which the operating and corn-dropping mechanisms are raised 'out of the' ground in turning the machine at the ends ofthe field.

IOO

L represents a sectional shaft, theinner ends of vwhich areifconnccted together by a tubular coupling, Z, and set-screws Z, while the outer ends -are journaled in and extend beyond the The object of the coupling is to lengthen or shorten the shaft L in accordance p with the adjustment of machine, to plant the corn in different-width rows. Upon said coupling Z is mounted a lever, Z2, secured thereon by a set-screw, and upon or near the outer endsof the shaft L, and inside of the beams A', are mounted pulleys M2 M, connected to and over which pass cords'or wires m m, also conn'ecte'd'to levers m m', carrying at their lower endsthe coveringwheels m2 m2, having 293,365 v s i the usual concave outer surfaces. The levers m' rn are provided near their centers with a series-of holes, by which they are adjustably and pivotally connected to the castings m"` m3,

all as clearlyshown in Figs. 2 and 3. Upon the outer ends of the shaft L, which extend through and beyond the beams A', are securely mounted small gear-wheels g', which mesh with the teeth g2 upon the inner and upper curved extensions, g3, of the cutters G. By pull ing lever ZIl backward, the shaft L will be turned so that the small gears will lift the cutters out of the ground, as also the covering-wheels, through the medium of the pivoted levers, connecting cords or wires, and the pulleys mounted on the sectional shaft, all of which is done when turning the machine at the ends of the rows.

NN represent the scrapers, connected to the cross-shaft a by setscrews, said Scrapersl being thrown into or out of engagement with the supporting-wheels by the foot-lever n,

connected to said cross-shaft, through the medium of lever a2 and connecting-rod a3.

On the face of disks C', and on the bars R It, connected to the outer ends of the transverse bars a a of the frame, are arranged numbers 0 l 2 3 4 5 6 7, lwith fractional marks between them, the numbers 0 0 denoting the dropping-points. As each'disk C has three dropping-holes, said numbersare arranged on the outer face of the disk between each of said dropping-holes, and, in connection with the stationary pointers I? P, the machine can be set at the ends of the rows without backing it up. When going out at the ends of the rows, a stake is set opposite the last hill dropped, and the machine turned around and driven forward until one ofthe numbers on the bars R comes opposite the stake. machine is stopped at number 5, which is opposite the stake, the machine already stand ing at its dropping-points,which will leave the stake five numbers ahead of the droppingpoint 0, the disks G G are rotated until number 5 comesoppositetothepointers ]?,when thedropping mechanism is let down (through the me diuni of lever 4) until the shaft C; with its boxes, rests on the castings b at the bottom of' the slots b3, and in starting the machine itwill drop the corn opposite the stake. In casethe machine has passed the stake and the dropping-point 0 on the bars R is five numbers forward of the stake, leave number 5 standing at the same point it was set for dropping five numbers forward, and the machine will drop at the second hill in front of the stake, which hill will be opposite the numbers 3 on the bars R before the machine starts forward.

Further description of the operation ofmy improved machine is deemed unnecessary, `it being obvious from the foregoing.
